About 2005 CE PUMD

There was a sample redesign in 2005. As a result, users will not be able to link all consumer units whose
participation spanned 2004 and 2005 sample designs. It is suggested that users use the 2003 and 2004
data or the 2005 and 2006 data for any micro-level longitudinal analysis. 2005 data users
should be aware that the 2005 first quarter (Q051) data in the 2004 data are from the old sample design,
while the Q051 data in the 2005 data are from the new sample design. Consequently, the data are not the
same. Other changes include:

2005 was the first year CE began collecting paradata, that is, data about the survey itself. While the 2005 paradata files were
originally released with the 2009 microdata (2009 was the first release of all paradata) these files are now available for download with the 2005 data here.

Beginning in 2005Q2 the UCCs for Coal were lumped in with the UCCs for Other Fuels forming new UCCs that encompass all "other fuels" including Coal, Wood and Kerosene. Also beginning in this quarter, the dated differentiation between colored and black & white televisions was dropped in lieu of a single TV UCC.
